1. Mental disorders are almost always _______, meaning they are influenced by multiple genes.

• A. environmental
• B. chemical circuits
• C. polygenic
• D. probabilistic

Correct answer: C

Rationale: The correct answer is C: 'polygenic.' Mental disorders are polygenic, which means they are influenced by multiple genes. This term specifically refers to conditions or traits that are caused by more than one gene. Choice A, 'environmental,' is incorrect as it doesn't directly refer to the genetic influence on mental disorders. Choice B, 'chemical circuits,' is incorrect as it is too specific and not a common term used to describe the genetic basis of mental disorders. Choice D, 'probabilistic,' is incorrect as it relates more to the likelihood or chance of something happening rather than the genetic influence on mental disorders.

2. What is a person's total genetic endowment?

• A. Phenotype
• B. Genotype
• C. Chromosomes
• D. DNA

Correct answer: B

Rationale: The correct answer is B: Genotype. A genotype refers to a person's total genetic endowment, representing the specific genetic makeup inherited from their parents. This includes all the genes and genetic information contained in an individual's DNA. Choices A, C, and D are incorrect because: A) Phenotype refers to the observable characteristics resulting from the interaction of genetics and the environment; C) Chromosomes are physical structures that contain genes, not the total genetic endowment itself; D) DNA carries genetic information but is just one component of an individual's total genetic endowment.

3. The understanding of genetic influences on behavior may never be fully achieved due to ________.

• A. the ease of researching to differentiate between the effects of the environment and genes.
• B. the likelihood that most behaviors are determined by the interaction of many genes and the environment.
• C. the reliance on twin studies in genetic research.
• D. our significant understanding of how genes impact brain chemistry.

Correct answer: B

Rationale: The correct answer is B because most behaviors are influenced by the interaction of multiple genes and the environment. Choice A is incorrect because it suggests that researching the effects of the environment and genes is easy, which is not the case. Choice C is incorrect as it focuses on a specific method (twin studies) rather than the broader concept of gene-environment interaction. Choice D is incorrect as the statement implies a high level of understanding that contradicts the idea that genetic influences on behavior may never be fully understood.

4. The humanistic perspective focuses primarily upon the capacity of the individual to ________.

• A. confront the dilemma of our deaths.
• B. be driven by unconscious motives.
• C. rationally explain our behavior.
• D. engage in positive self-growth.

Correct answer: D

Rationale: The humanistic perspective, as highlighted by proponents like Carl Rogers and Abraham Maslow, emphasizes the inherent drive of individuals to achieve self-actualization and positive self-growth. It focuses on the individual's potential for growth, self-improvement, and fulfilling their highest capabilities. Choice A is incorrect as the humanistic perspective is more concerned with personal growth than with addressing the fear of death. Choice B is associated with the psychodynamic perspective, which focuses on unconscious motives. Choice C is related to cognitive-behavioral approaches that emphasize the rational understanding of behavior.

5. Normal human cells have ________

• A. twenty-two chromosome pairs and one pair of sex chromosomes.
• B. twenty-one trisomy chromosome pairs, one autosomal pair, and one pair of sex chromosomes.
• C. twenty-one chromosome pairs and two trisomy chromosome pairs.
• D. twenty-three chromosome pairs.

Correct answer: A

Rationale: Normal human cells have twenty-two chromosome pairs and one pair of sex chromosomes. This is the correct answer as it accurately describes the typical chromosome count in human cells. Choice B is incorrect because it mentions 'twenty-one trisomy chromosome pairs,' which is not characteristic of normal cells. Choice C is incorrect as it suggests having 'two trisomy chromosome pairs,' which is abnormal. Choice D is incorrect as it states 'twenty-three chromosome pairs,' which is not the standard count in normal human cells.
